If we can’t find a print of the film that would prove that this alternate edit of the said sequence had existed, then perhaps we can look at the ‘spotting’ notes of music editor, the late Kenneth Wannberg.
Right after a composer is hired to a film, he and the director get together to view the film—from start to finish—and find areas in it where music is needed. This period is known as a spotting session. The music editor is also present during that session as he must take notes on which group of footage needs music.
After the meeting, the music editor takes his notes from that meeting and prepares a typewritten list of action for each music-cue that the director wants. Each action has a time-stamp on the left side. This paperwork is called the spotting notes. It would look like this:

Since Kenneth Wannberg was involved in ‘Star Wars’ for composer John Williams, Wannberg would prepare such a typewritten list for the composer. If this alternate edit for the said sequence existed, then, certainly, one of the shot’s description in Wannberg’s spotting notes would read like this.
